How To Check Power Steering Fluid

Check your power steering fluid only when the engine is warm. If the engine is not warm, you probably will not get an accurate reading.

If the fluid level is between the MIN (Minimum) and MAX (Maximum) marks, you have enough. If you need fluid, add only enough of the proper fluid to bring it in between the MIN and MAX marks.

If your power steering fluid level is low, this can cause the brake or service brakes soon warning lights to come on. In addition, the steering effort and emergency brake distance could increase.

If either light remains on after you have added power steering fluid to the proper level, then shut off the engine for 10 seconds. This should reset the brake warning lights. If one or both lights stay on, see "Hydraulic Brake System Warning Lights" under Brake System Warning Light for more information.

What to Use

To determine what kind of fluid to use, see Part C: Recommended Fluids and Lubricants .

Notice: When adding power steering fluid or making a complete fluid change, always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.
